If you look at the measures dimension in eazyBI, there are two members "Issues resolved" and "Sub-tasks resolved". When I reported on "Issues resolved" it seemed high, so when I drilled through to Issues, it looked like sub-tasks were included in that measure.
Are sub-tasks considered to be a type of issue? It doesn't make sense to me to include them in the "Issues resolved" measure.
I just looked at creating a calculated member, but subtracting from "Issues resolved" the number of sub-tasks created or sub-tasks resolved doesn't give me the correct value either.
